Linux host freezes when started bridged network to a kernel bridge device => Fixed in SVN

Description

My linux host freezes right after I start a guest that uses bridged networking, bridged to a kernel bridge device (br0, bridge-utils/brctl). It works fine with other devices (eth, tap). This problem did not exist in previous versions of VirtualBox (3.x).

I created a bridge device with bridge-utils, set it a static ip, configured VM's network adapter to connect to the br0 device (win xp) and after a few seconds the whole host system hangs and the capslock and numlock leds light up...

Looks like this might be a duplicate of #7908.
I will attach my vboxnetflt.ko as requested in the other ticket.

Guizmo: using a tap device to bind to, instead of a bridge, works somewhat better. It crashes under load, but not immediately. I'm currently successfully using the VDE2 backend, which runs in userspace. The vde_switch then binds to a tap interface on the host.

This occurs on Fedora 14 host (kernel 2.6.35.10-74.fc14.x86_64.)
I tried with centos 5.5 and ubuntu 10.10 guests.
If the guest use a bridge, the host freeze with black screen and it's not possible to change the level of the host (CTRL+ALT+FF3 for exemple).
Whithout bridge, no crash happens.
